Old school video games in your browser

Game Oldies

Through the miracle of Java, Game Oldies brings you all your favourite video games to play in your browser window for free. No emulators are needed. They have tons of games from the Nintendo NES, Sega Genesis, Game Gear, Game Boy, Colecovision and more.

It did run a little slow on my machine, but this is such a neat idea. Now how long will it be until XBox 360 games will be playable in your browser window for free?
